I would like "shutdown -p now" actually power off my ATX system.
The shutdown(1) manual page mentions you need hardware support for
this, but does not list the devices needed for the "-p" option to
The LINT kernel config file mentions something about the PIIX power
management chipset (which my BSD box has). If I compile this in the
kernel, will shutdown(1) use it?
Some pointers to documentation on this would be very much appreciated.
